Abstract:
A novel tobacco-curing system with a solar-assisted heat pump was proposed. The proposed system has various advantages, such as reducing energy consumption and pollutant emissions and enhancing the stability of system operation. The thermal characteristics of the system under different climate conditions were analyzed, and the economic and environmental benefits of different tobacco-curing technologies were compared. Results indicated that the dehydration rate, the mass flux of exhaust air, and the heat load of the novel tobacco-curing system in different months had similar changes with the baking time, and all reached the maximum in the later stage of color fixing. Compared with the power saving rate of a heat pump tobacco-curing system, that of the novel system reached 25.9%-35.1%. The dry leaf curing cost of the novel system was only 0.86-1.06 yuan/kg, which can reduce the cost by more than 60% compared with traditional coal-burning tobacco-curing systems in China. Compared with other parts of the tobacco leaf, the top leaf had the lowest dry leaf curing cost due to its highest mass of dry leaf. The payback period and the annual CO2 emission reduction of the novel system were 3.0-3.7 a and 15 586 kg, respectively.
